Background The Duruöz Hand Index (DHI)  has 18 items of daily activities questions. It was developed to assess the functional disability of rheumatoid hand and cross validated for some other arthropaties of the hand (osteoarthritis, systemic sclerosis, carpal tunnel syndrome, stroke, flexor tendon rupture etc.).
Objectives To assess the usefulness of the DHI to evaluate functional disability of hands in geriatri population.
Methods Subjects aged more than 65 were recruited into the study. The local or systemic diseases which may affect directly the hand function were exclusion criteria. Demographic and functional characteristics of subjects were evaluated. The functional assessment was performed with DHI, Hand Functional Index (HFI), Health Assessment Questionnaire (HAQ), Purdue Pegboard (fingertip dexterity and hands coordination) and grip strength (JAMAR) and 3 kinds of pinch (tip, lateral, chuck) strengths (JAMAR). The DHI was correlated (Spearman’s correlation coefficient) with the other functional parameters to assess the convergent validity and with non-functional parameters to assess the divergent validity. p<0.05 was significant.
Results Fifty patients (33 female) with mean age 72.6 (range: 65-90) were recruited. The average score of DHI was 16.32 (SD: 17.57) and 26.0% of patients had zero score (without disability). The DHI had not any significant relation with demographic data such as age, hand dominancy, alcohol consumption, smoking and DHI has poor or fair correlation with fatigue level and Pittsburg Sleep Quality Index (divergent validity). The DHI has significant and good correlation with Health Assessment Questionnaire (HAQ), Hand Functional Index, Purdue Pegboard scores, grip strength and 3 types of pinch strengths (convergent validity). The strongest relation of DHI is with HAQ (rho: 0.782; p<0.0001).
Conclusions The DHI is practical scale and it is useful to assess the functional disability of hands accurately in geriatric population.
